Is Substack down, or is it just you?
Multiple independent check rounds from rimetry's monitoring infrastructure, run seconds apart.
Our checks reached Substack successfully in every round of the last check cycle.
| Check round | Last check | Success rate (24h) | Avg response |
|---|---|---|---|
| Round 1 | Reachable | 100% | 818 ms |
| Round 2 | Reachable | 100% | 748 ms |
| Round 3 | Reachable | 100% | 588 ms |
| Round 4 | Reachable | 100% | 671 ms |
Based on 3,280 automated checks in the last 24 hours. Each round is an independent pass over the same endpoint, seconds apart — a single failing round is not an outage; repeated failures across rounds are.

About Substack
Substack is a publishing platform used by writers to create and distribute email newsletters and manage paid subscriptions. Authors use the interface to draft posts, while readers access content via the web or mobile app and manage their delivery preferences. Technical failures usually impact the distribution of emails, the loading of high-resolution images within articles, or the functionality of the billing system for premium subscribers. Rimetry observes the accessibility of Substack's hosting and delivery layers to ensure that users are alerted to any significant disruptions in service.
Problems with Substack can affect website, article pages, subscription & paywall independently.
